5.1 Inserting Circuits

In this section, you make a few edits and corrections to the circuit to add some features. You will begin by inserting a circuit.

In this example, first assume a flickercircuit for which the lighting interval hasbeen set to 3 seconds by writing an ONdelay timer directly. Then you will changethis circuit to such a configuration thatthe data for the lighting interval for thecircuit is set to the data register inadvance and the ON delay timerreferences the value in this data register.

First, add a circuit in front of Circuit 2.To add a circuit, use the Line insertionfunction.On the Edit menu, click Edit Mode.In Edit mode, move the box cursor to theinsertion point. Then, on the Edit menu,point to Insert and then click Line on thesubmenu.


5. Advanced Editing

A blank line will be inserted. The existingcircuits will move down from the next lineon, as shown in the figure.

You will create a circuit on this line to setthe lighting interval.Check to make sure that the box cursor isat the beginning of Circuit 2, then start byplacing a NC contact of R0000.

When you have placed the NC contact,place the symbol for setting data to thedata register.Select the "Mov" item and then click tothe right of the B contact. The Movinstruction symbol will be placed there.

Basic Operation 55

5. Advanced Editing

Two operands are entered for the Movinstruction symbol, a transfer sourceregister or a constant and a transferdestination register.In this example, we will assume that thedata for the flicker circuit lighting intervalis determined in another program (forexample, to match the level of erroroccurrence) and stored in RW020, andwe will transfer this data to data registerD0000.Enter the two operands on the keyboard.

The line from the Mov instruction symbolto the right bus is unconnected, but it willbe automatically connected when theprogram is written like the ENDinstruction issued.

Now you will do a little editing on circuit 3.In this example, you will change thesetting for the ON delay timer from aconstant to the data register number.Move the box cursor to the first operandin the ON delay timer instruction in thethird line of Circuit 3, then enter "D0" andpress the Enter key.This will cause the ON delay timer settingto be replaced with the value in dataregister D0000.When the operand has been properlyentered, select Write to write the data tothe controller.

Check to make sure that the new circuithas been added to Circuit 2 and thesubsequent circuits have moved downaccordingly. Then quit Edit mode andreturn to Monitor mode.

7.2 Sampling Trace

The controller has a function that enables you to sample and display changes in device status and register values during program execution. In this example, you will use this function to check on device and register trends in the flicker circuit.

7.2.1 Setting the Sampling Buffer

In order to sample data, it is necessary to secure a buffer, i.e. the memory area in whichthe sampling data will be stored. This is set in the system data.

On the PLC menu, click SystemParameters. The System Parametersscreen will appear. Click Memory Size &Scan Time.Then set the Sampling Buffer Size in theMemory Size area. For the T3, thesampling buffer may be set up to amaximum of 8KW.

- On the T3/T3H the F register or an IC memory card is used for the sampling buffer. Note that setting a sampling buffer will decrease the amount of memory used by the program by the amount of the buffer setting.- On the T2, IC cards are used to store sampling data.- When performing a sample trace on the T2, be sure to insert an IC memory card andassign the memory card using the "I/O Card Allocation" procedure. The sampling buffersize is fixed at 8KW.

- For the T2E/T2N, the sampling buffer size is fixed at 8kW and uses internal memory.- For the T1/T1S, the sampling buffer size is fixed at 1kW and uses internal memory.- For the S2T, the sampling buffer size is fixed at 8kW and uses internal memory.

7.2.2 Setting the Sampling Condition

On the Debug menu, click Sample Trace.The Sample Trace dialog box will appear.

The Sample Trace dialog box is used to setthe registers for data sampling, thesampling trigger condition and other data.

First check to make sure that thesampling buffer size set as system data isdisplayed in the upper left-hand corner.

In this example, you will set the triggercondition.The trigger condition sets the timing fordata sampling during program execution (during scanning). The trigger conditionis specified as a device and a registercondition, such as when the device statushas changed or when the register hasreached a certain constant value.

In this example, you will set the trigger tobe activated when the timing relay(S0040) goes ON or OFF.

Move the mouse to the Trigger Condition text box and enter "1".This designates how many times sampling is performed when the sampling conditionsare fulfilled. Setting the value to "1" causes sampling to be performed for each scan thatfulfills the trigger conditions.Move the mouse pointer to the right and enter "S0040" for the sampling device. Thenselect the operation condition to one of the choices in the list box (Device ON, DeviceOFF or Device Change). In this example, you will set it to Device Change.

Basic Operation 73

7. Beyond the Basic

When the trigger conditions have beenset, move the mouse pointer to theSample Target area.This area is used to designate thedevices and registers for sampling. Enterthe device and register numbers.In this example, enter T000 and T001 forthe registers and R0002, R0003 andS0040 for the devices.When the settings are complete, click Setto save them.As a result of these settings, when theS0040 relay changes from ON to OFF orvice versa, the current values for timer 0and timer 1 and the ON/OFF status ofR0002, R0003 and S0040 will besampled.

The sampling conditions have now been set. Click Enable at the top of the dialog box.This completes the preparations for sampling.Execute the program using the key-switch on the T3 or PLC Control. When theprogram is ready for execution, click Start. Sampling will begin. When sampling hasbeen performed for 10 seconds or more (and flickering has begun), click Stop.Sampling will stop and the program operation status will be stored in the samplingbuffer.

Error Message Overview

There are 4 types of error messages as follows.

A. Operation Error

These error messages are displayed for the T-PDS operation which you attempt to do.Communication error between T-PDS and PLC is also included in this type.It is displayed in the message box.

B. Compile Error

These errors are detected in the T-PDS when edited program is compiled.It is displayed in the message box.

C. PLC Status Line

When the T-PDS is on-line mode, the PLC's operation mode (RUN, HALT, or ERROR)and alarm status are displayed in the status line.

PLC modeRUNHALTERROR

Alarm statusPROG: Programming enabled.PROT: Program is write-protected.LOAD: Under program down-loading.DIAG: User diagnostic instruction was executed.SCAN: Time-over for the constant scan setting.TL-F: TOSLINE-F10 error.TL-S: TOSLINE-S20 error.BATT: Battery alarm.


Error Message

D. Event History Table

When the PLC detects some abnormality in its diagnostic checks, it is recorded in thePLC memory called Event history table. In the Event history table, the last 30 eventmessages (15 in case of T1/T1S) are stored in this table. The contents of the Eventhistory table can be monitored on the T-PDS screen by [PLC] [Event History] menu.

<Event History Table>

Date The date the error occurred (requires RTC/calendar).Time The time the error was detected (requires RTC/calendar).Event Description of what occurred.Count Number of retries to correct the event.Information Additional information about the event.Mode The operation mode when the event occurred.DOWN The event caused the controller to enter the Error Mode.

[Save] button is used to save the Event history table contents into the disk file.

Usually a PLC goes into the error mode when one of its diagnostic checks determinesthat something has occurred which interferes with normal operation. When a controlleris in the error mode, all outputs turn OFF and operation stops. Nothing else is possibleuntil Error Reset is executed. The basic recovery procedure is:

(1) Execute Error Reset (reset the error and put the PLC in the Halt Mode).(2) Study the Event History Table.(3) Make the necessary corrections.(4) Return to the Run Mode.
